Recommended Posts

Hello!

does anyone have any tricks or tips when replacing/repairing military spec ignition leads? 

Im currently restoring a thornycroft fitted with the Rolls-Royce b80. 

This is what I have.

No idea about the question, but what breed of Thorneycroft are you working on?

Wouldn't be an LMD  trench digger by any chance?

Looks like an RAF Nubian fire tender and I have a feeling that the B80 engine is an early BSF one.

Yes you can renew the HT cables from within their shrouds, problem is the old cable tend to go gummy and stick a bit. Replace with copper core 7mm HT lead.

Ahh that’s a shame! 

It’s a thornycroft Nubian mk5 fire tender.

Replacement of leads are failry easy to pull through using a silicon grease /spray on old and new  copper leads  all the metal connections can be wire brushed before fitting

all the best
